Having now described this invention and its use, I claim:-

1. In 'a controllable steam heating apparatus, the combination with a housing open at the bottom, of a motor case in the housing, a motor arranged in said case, means provided with a control valve for serving steam to themotor, a radiator in said housing, said radiator being in open communication with the motor case whereby steam acting upon the motor is thereafter delivered to the radiator, a fan rotated by the motor and arranged to impel air from the open bottom of the housing through the radiator, said radiator having a downwardly extending discharge pipe for the water of condensation, an expansible and adjustable diaphragm device located near said pipe and controlled by the temperature of condensation, means for transmitting the movements of the diaphragm device to the said steam control valve, a water tank open at the top and arranged in the lower part of the housing, a tube constructed and arranged to conduct water of condensation from said pipe to said tank, said tank being provided with an overflow tube connected with the said condensation pipe at a lower point, said housing having front perforations, and a shield constructed and arranged to direct air from said perforations upon the open top of said tank.

2. In an apparatus for controlling and serving heated air, a vertically arranged external housing open at the bottom, said housing having at the top an internal chamber constructed with an extended portion next to the top of the housing, a steam driven motor revoluble within the said chamber, means for directing steam to the motor, a revoluble air fan located outside the said chamber and within said housing and arranged to be revolved by said motor, a radiator arranged before said fan and within said housing and in communication with the said extended portion of the chamber, a condensation pipe extending downwardly from the radiator within the housing, an adjustable register in the front of the housing before said fan, an open top air moistening tank located within the housing and having means in communication with said condensation pipe whereby the tank is supplied with water, a tube connected with said tank and with said condensation pipe whereby the overflow of the tank is prevented, and an air shield within the housing whereby air from the lower portion of the housing is directed upwardly and over the open top of the said tank.
